No it is not. It sure can run any game you like. Not right now it do not benefit in games. But in future it is maybe other story. CPU performance is not anymore question of CPU frequencies. And there are couple games in market that benefits the HT. It is more likely that there will be more in future. You can't overclock 3570k to be faster than xeon.
It is not faster when you overclock it to 4.0GHz why is that? And if must have more overclockin like 4.5 to 5.0GHz it do not come cheap. So you are telling as well that the 3770 and 3770k is no good CPU? They are too faster than 3570k.
I was only thinking that it is better take faster CPU if you can even if you do not overclock. I think faster is better. If you overclock or not. And it is sure thing. Overclocking is not. 212 EVO makes it to 4.2 GHz tops. And still if someone buys 3570k and do not overclock it. You still have faster CPU if you buy xeon
HT and 8 cores come this case for free.
And that is not bad thing. 3570k price is £167.99 and xeon is £172.79+so 5£ more. Too much? Maybe. maybe not.
but overclocking option is not cheap. You need good CPU cooler and more expensive MoBo.
And the SSD if you want cheap take that crucial. If you want fast take samsung pro. Not that TLC samsung.it is not good choice.
